Guide To GAS Boilers

When you are on the hunt for a new boiler, you will be faced with a lot of choices. Before you go out looking, you need to look at the various boiler options. This will help you to decide which boiler will be right for you. There are a lot of reasons why you may need a boiler, including:

  • A new home requiring a boiler
  • Unhappy with expensive bills
  • Repairs on an existing boiler will cost more than replacement
  • Boiler is old and could be dangerous

Why Choose A Gas Boiler?

Gas boilers are the most common way to heat our water and homes. Fuel type is just one of the many choices you’ll make when choosing a boiler. It’s an overwhelming decision, though, so you need to know all the information to make your choice. Most people choose gas boilers for their homes. This is because a steady gas supply is piped to these homes. So, choosing a gas boiler is a sensible decision.

The Types Of Gas Boiler

Gas boilers – like other boiler types – are the spotlight for your central heating system. They can heat water and pump it throughout the house. They do this through radiators and pipework. There is a continuous supply of natural gas that feeds the boiler using a mains connection outside the home. When you switch the boiler on, the gas lights and heats water for you.

The type of gas boiler that you invest in largely depends on the size of your home. Smaller houses find that the combi-boiler is ideal most of the time. This is because they are compact and easy to install; they also don’t need a huge water cylinder. Combi boilers provide heat and hot water on demand, so they’re an ideal choice for smaller houses. However, larger households may prefer to use system boilers – as would those who want to run the hot water from more than one tap. So, what types of boiler are there out there?

Combi Boiler

These are a sealed system boiler, providing hot water for taps and central heating. The water is heated directly from the mains system on demand. This means there is no need for a water cylinder. The advantages here are that combi boilers are easier and cheaper to fit. Water is also delivered at pressure from the mains; so you can enjoy a proper shower! The disadvantages come from the fact it’s a priority system. This means you can’t run the hot water from two bathrooms at once. Otherwise, you end up with reduced flow.

System Boiler

These boilers are fitted to sealed heating systems. However, they do rely on storing hot water in a cylinder. This means they can pass over hot water to more than one room using it at a time. You won’t need a cistern installed in the loft, as the expansion vessel is already built it. These boilers are perfect for larger homes with more demand on the hot water and heating. Their installation is fast and cheap. Boiler water flower rates are also high, so hot water is instant for use. The downside of a system boiler is the fact that, if overused, the hot water will run out. It’s also more likely to be prone to issues like pressure loss.

Regular Boilers

These are boilers that are bought as replacements for houses with a system of open-vented heating. This means the homes that are supplied by feed and expansion. In the same way system boilers work, they store water. Regular boilers require a water cylinder in the same way that system boilers do. They’re a good option as the water comes at a high flow rate, with hot water instantly supplied. Those who love a power shower will love this boiler, as it provides the cold feed and an electric pump separately. The only real downside for a regular boiler is that they can be more expensive to install. They can also suffer low pressure, and the hot water can run out quickly if not managed.
